How to build it
**( 1 ) **Assemble the outhouse over a hole that you’ve dug measuring 3x3x3 feet. Lay down a 48×48-inch foundation frame of 2x4s (with space for the hole). Construct a 48×48-inch double-layered floor joist box, using 2×8-inch treated lumber (joists running front to back) and set this atop the foundation. Cover the joist box with a 5/8-inch exterior plywood floor, centering a 12×24-inch opening on the back side. Then make a bench seat from 2x4s, 24 inches wide and 18 inches high, covered with 1-inch-thick boards. The toilet seat opening is 10×12 inches.
( 2 ) Make the walls 41×48 inches, 84 inches high at the front and 78 inches high at the back. The walls, roof, sills, and base are 2×4 frames covered with 1-inch-thick shiplapped boards. Create a 30×76-inch doorframe for a vertical shiplapped siding door (with a Z-shaped 2×4 brace). Attach the door with brass hinge plates. The roof assembly-60-inch 2×4 rafters sandwiched between two planks of 5/8-inch exterior plywood-overhangs every side by 6 inches. (In the illustration the bottom panel is omitted to show the interior construction.) Top the roof with shingles or galvanized aluminum.
